seeds Two-part question

It's been a while since I started a new seed tray, which I'll be doing this week, so I had a two-part question:
  1. My initial plan is to put the seed tray I'll be starting this week outside on the balcony. Since the outdoor temperatures are already getting into the upper 70's to low 80's (lows are in the mid to upper 60's for the foreseeable future), do I really need to put the seed tray on a heating mat. The info printed on the heating pad I currently have says it will heat the root area to ~10-20 degrees above ambient air temperature. I definitely don't want to overcook the tray & starter pellets before the seeds have a chance to germinate.
  2. I had some success my last go 'round using a dash of hydrogen peroxide in the water I'll be using to soak the seeds overnight to aid in germination, but I'm drawing a blank as to the amount to put in. I know it's not much, I think it was a couple teaspoons at most. Feel free and let me know if that sounds about right.

What is the first question?

I haven't tried a heat mat yet.
I think it's ok to not use one.
I still want to try a heat mat in the future.

Guess it depends on the Heat and the Heat Mat.

Sorry if it was unclear. Basically, my question was, with the temperatures outside being what they are (upper 70's to 80's Fahrenheit), do I really need to use a heat mat to help with germination?

My underground grow room is kept at mid 70s.
My grow mats are set to 85 Degrees.

As soon as my seeds pop, ilI lower the mats to 70 Degrees for gentle bottom heat.
I may get germination in the heated room without mats, however I believe a quick germination may
be better for overall seedling health. Too many variables in cool soil, I don't need more problems getting them to pop.
